The Eastern Bluebird (Sialia sialis) is a medium-small bird (16-21 cm [6-8 in] long; 28-32 g [1-1.1 oz]) with a round belly and head. Males are bright blue on the tail, wing, back, and head; rusty on the breast and sides; and white below. Females are grayish above with blue on the tail and wings and an orange wash on the breast. It catches insects on the ground in open country near trees. It ranges across the eastern US and breeds in southeastern and south-central New Mexico. The Eastern Bluebird will experience a high degree of climate exposure and has a high adaptive capacity. Overall, it has a Climate Change Vulnerability Index ranking of Less Vulnerable under both Representative Concentration Pathway (RCP) 4.5 and RCP 8.5 Scenarios. The Eastern Bluebird’s climate change vulnerability is impacted by factors related to movement and life history, which influence its ability to shift in space and persist in place.
